'to throughout the extentof "itsrheel seat yportieri -`In Vorder y*torub out any wrinkles that may `110 have occurred at the heel end of theupper there is provided a wiper for downwiping the back seam. Asillustrated, the wiper is substantially the same as that disclosed inPatent No. 1,443,- 288, above referred to. There is also provided poweractuated means for further actuating the spindle, after the. operatorhas swung Iit toward the machine into operativeposition, in order tourge the last and upper rearwardly against the back seam wiper, saidwiper, in the machine herein illustrated, operating as an abutment toarrest such rearward movement of the last and upper. The power actuatedmeans for further moving the spindle toward the machine may besubstantially the same as the'hook disclosed in Patent No. 1,602,618above referred to.

In accordance with a feature of the invention there is provided meansfor clamping the welt and holding it against downward movement duringthe actuation of the back seam wiper to downwipe the heel end of theupper. Said clamping means may consist of the welt presser and itsopposing wipers, above referred to. Since the downwiping of the heel endof the upper is accompanied by a rearward movement of the last and upperitis desirable that the clamp whichvholds rthe welt against downwardmovement be afforded a suicient lengthwise movement to permit it totravel rearwardly with the last and upper and,l accordingly, a furtherfeature of the invention comprises a clamp for clamping the welt andholding it against downward movement, ksaid clamp being arranged topermit a movement of the last and upper toward the wiper after theweltfhas been clamped.

Another featureV of the invention consists-in an organization includingmeans, for example, tack drivers, for inserting fastenings through thewelt and upperk and into the last bottom at opposite sides of theheelseat, wipers for engaging the upper and welt at therwelt crease, whichmay be thesarneV as the wipers which cooperate with the welt presser toclamp the welt, and means actuated by the wipers for determining thearrangement of said fastenings widthwise of the heel seat. Asillustrated, the wipers are yieldingly brought toward, each othertopredetermined limits and are spread apartpby the engagement of theheelend of a last 'and upper therebetween.

`It is desirable that the tackers partake'of the movement ofthe wiperslengthwise of the last, and accordingly, a feature of theinventionconsists in an organization wherein the tackers are arrangedfor movement lengthwise of the last with the'wipers. There is alsoprovided, in accordance with a further feature of the invention, meansfor varying the relative position of the tackers and the wiperslengthwise of the last inorder that the central heel seat tack may beinserted as close'to vthe seam uniting the welt and upper as may bedesired without danger of driving the tack through the` seam itself.

It is desirable that the `tacks whereby the welt and upperv are attachedto the shoe bottom be leftr upstanding above the surface of the welt inorder to facilitate their removal. Accordingly a feature of theinvention consists of an organization comprising a plurality of wipersfor overwiping the heel end of a pre-welted upper, a plurality oftackersfor driving tacks through the welt and upper at opposite sides ofthe heel end of the upper, a centralheel seat tacker for driving a tackvthrough thewelt and upper, an

to the, Aside tacks..

actuator for said tackers, and an adjustable abutment for arresting theactuator.

It has been learned that a variation in the position of the tackerslengthwise of the last varies the extent to which the central heel seattack is left upstanding above the work relatively t 5 Insome,.cases, thecentral heelI seat tackfis: left' upstandingwhile the side tacks aredriven completely into the work unless "provision is made for a relativeadjustment of the strokes of the drivers. Accordingly, there isprovided, in accordance with a further feature of the invention, anorganization including means for relative adjustment of the strokes ofthe drivers whereby any variations in the extent to which said tacksremain upstanding above the surface of the welt may conveniently bechanged. -1

It is desirable that the tacker nozzles be suiiciently remote from thework after the tacking operation to ensure that the work, with the`upstanding tacks inserted therein, can be withdrawn from thegmachinewithout interference from the tacker nozzles. Accordingly, anotherfeature of the invention consists in an organi' zation including a Weltpresser `arranged for movement heightwise of the last and connectionsbetween the welt presser and the tackers whereby lthe heightwisemovement of the welt presser is imparted to the tackers.

These and other features of the invention including various ynovelconstructions and combinations of parts will appear more fully from thefollowing detailed description when read in connection withv theaccompanying drawings, and" will be pointed out in the appended claims.l

InFig; 1 of the drawings is shown a side elevation of ra, machinehaving, in general, the organization disclosed in the patentsabove-identied to whichreference may be had for a detailed rdescriptionof parts which are not fullydescribed herein.

The illustrated machine is provided Vwith a base or column 20 to whichis pivoted at 22 an arm or carrier 24 upon which is yieldingly-supported a hollow work supporting spindle 26.

The vspindle 26 is maintained parallel to the carrier 24 by parallelmotion links 28 and 30 which permit a limited heightwise movement of thespindle. :The links 28 are pivoted at their rearward ends, by means of across pin 29 to the rearwardly extended upper extremity of the carrier24 and at their forward ends to a cross pin 32 arranged to extendthrough the-spindle lil) jviis flO feo fjusting. .the ,position .of thepresser foot -63 yin zthe threaded into an internally threaded socket inthe `tubular rmember 34. In order .to accommo- .date the 'transversecomponent of the heightwise movement of the spindle 26, the forwardexten- .sion 44 of the vcarrier is provided with an oversized .hole forthereception of the spindle and a `washer 48 is preferablyprovided toforma seat for the spring 42. It will 'be seen thatupward movement ofthe spindle ;by the spring 42 is lim- `itedby thecollar and it will alsobe seen that thercompression of the spring may conveniently be adjustedby the capstan sleeve 46. .At its upper end Athe spindle 26 carries aheel post or vlast pin 50 (Fig. 2) slidably mounted within the upperextremity of the spindle .and yieldingly :supported therein upon acompression spring 52 resting upon a screw54 (Fig. 1) passing throughthe spindle. The'heel post 50 is provided `with a last pin 56arranged'to supporta last in inverted position. Outward swingingmovement of the spindle 26 is limited zbya rod 55 pivoted at 57 to thecarrier 24 and arranged to extend through an opening in the machinecolumn 20. .On the rod inside the column is a spring 59 which is heldonthe rodby afnut 61 and engages `the'column yieldingly to limitoutwardinovement of the jack spindle.

In order to depress the last to bring the last bottom into apredetermined elevation as the jack spindle is swung to bring theY shoeinto position tobe operated upon, a'depressor 58, (Fig.

1) which may `be constructed and yarranged as disclosed in Patent No.1,602,618, Jabove referred carrier 24. Since the ypull of thespringis'in an upwardly and rearwardly inclined direction, one

component of the pull tends to lift the depressor and the other `toswing the depressor'outwardly upon the cross pin 32 as a pivot. Thedepressor `has a predetermined downward movementkim- `parted thereto bythe action .of a link 62 pivoted, `at `one end thereof, approximatelymidway `of the height of the depressor and at its opposite end to an arm64iextending forwardly from the machine frame at an elevation such thatthe link `62 normally extends 'downwardly and forwardly from its pivotalconnection therewith. The swinging movement of the jack spindle 26 isimparted to the depressor 58 by the engagement of the spindle with thehorizontal arm of a crank pin 66 forming the pivotal connection of thelink 62 with the depressor 58, said crank pin having provision forrotative adjustment in order to 'vary `the stroke of the depressor. Thedepressed position-of kthe .last may be-varied by ad- .,extension 32 towhich is `pivoted `a link '84 ar- -depressor bar.. 58.

. Inf the-illustrated Lmachine means is `provided for a :preliminaryheightwise adjustment lof the last-pin;v said ,means comprising .a.sleeve .68 .(Fig.; 2) slidably, mounted on the :spindle 2.6` and.provided at its lower end with va series of `rounded notches 70arranged progressively about the sleeve, the extremities of saidynotchesbeing .positioned `at, progressively varying elevations. The.heel post 50 is provided witha screw 72 extending` outwardly from theheel -post into positionto engage alternatively within the notches 70formed in the sleeve 68. .The screw 7.2 is `arranged to extend throughaslot 74 formed .in

lthe'spjndle 26 and extending heightwise thereof .in order to permit alimited heightwise move- ,mentor the heel post 50. The sleeve 68isnormally held against fa collar '76 Asecured tothe spindle 26near itsupperV end.

- As the spindle is'swungl in *and `the depressor 58 is actuated tobring the lastbottom into `a predetermined elevation the spring 52 iscompressed, the heavier spring 42 `remainingsubstantially unaffected. Asthe spindle :nearsthe limit of its inwardfinovement a latch member 17.8is automatically Vactuated to engage ratchet teeth 92 formed in theheelpost 50 vinorder to `lock the heel postgto, the spindle, `whereby `aiurther depression of the "heel post by ithe'welt pressing meanshereinafter described is resisted by the relatively `heavy spring 42.The latch member 78 is pivoted to a bracket 80 secured to the spindleand is provided with a downward ranged-to extend through and tofbesupported by the machine column 20.V A .compression -spring is mountedon theV link 84 .betweenfa `collar 8 'and the front of the machinecolumn. AWhen-the spindle is in its `retracted position, as shown inFig. l, the rearward end ofthe compression spring 86 is spaced away fromthe front of the machine column suiciently to permit the spindle to.swinginwardly almost to the limit of its movement, before the spring 86engagesthe machine columnin order to actuate the latch member'76. Theheel post 50` is thus-'permitted to,` move downwardly relatively'to thespindle throughout substantially the full extent of `the actuation ofthe spindle in order to bring the vlast intothe desired elevation.The-'latch mem- Lberf is normally held in its inoperative positionbyvacompr'ession spring 90 (Fig. 2) seated infa socket formed in thelatch member 78 `and arranged to press against Vthe spindle 26. An`opening .formed in the spindle through which the latch member 76 swingsin order to bring itlinto engagement withratchet teeth 92 `formed in theheel post. The ratchet teeth are maintained in` position to be engagedby the latch member 78 'by'. the engagement of the screw 72 within ltheslot 74 in the spindle, the width of said slot being substantially equalto the diameter of the screw in order to prevent ,the heel" post `fromturning. l

An upper 97 with a welt v99 stitched thereto is loosely arranged upon alast 93, and the last, with the pre-welted upper arranged thereon, is lplaced on the `last pin 56. -The operator then arranges the upper toposition it substantially as shown inv Fig. 1 and, while holding theupper to the last, swings the last with the jack spindle 26 toward ythemachine, nothing further lbeing required, of they operator except tomovethe spindle.

The depressor 58, by the mutual relative movement between it and thespindle, first assumes a position over the last and is then moveddownwardly to depress the last to the proper Working position relativelyto the operating instrumentalities of the machine.

As the heel end of the last and upper approach the machine they passbetween the inner edges of a pair of wiper plates 94. As shown in Fig.3, the space betweenthe inner edges of said plates is somewhat less thanthe width of Vthe heel seat of a last and, consequently, as the last andupper approach the machine the upper engages the wiper plates, spreadingthem apart from each other.

sides'of the heel seat. The engagement ofthe rear end of the last withthe wiper plates 94 also operates to determine the position of a centralheel seat tacker 98 lengthwise of the last, they operative positionofthe wiper plates 94 being adjustable lengthwise of the last in orderto vary the adjustment of the central heel seat tacker, as hereinafterdescribed.

The later portion of the swinging movement of the spindle 26 to bringthe last into position to be `operated upon is utilized to start thepower Letters Patent No. 1,602,618, above referredvto.

Briefly described this mechanism comprises a rod 104 pivoted at 57 tothe carrier 24 and mounted to slide through the lower end ofl an arm 106pivoted to the machine column. The rod 104 has a collar 108 securedthereto in position to engage the arm 106 as the jack spindle approachesthe limit of its inward movement, thereby swinging an arm 110-andcausing alatch member (not shown) carried by said arm to engage a plate114 secured to the clutch rod 102 thereby imparting the desired downwardpull to the clutch rod to trip the clutch.

During the initial stage of the operation of the machine a welt presser116 (Fig. 2) is actuated to straighten the welt about the heel end ofthe last in order to arrange it in parallel relation to the heel seat.The straightening of the welt is effected by depressing the last andupper against the resistance of the spring 42 which yieldingly supportsthe spindle 26, the ydepression being arrested by Vthefwiperv plates 94which are constructed and arranged to embrace the heel end of the lastand upper and have an undercut bevel formed in their upper engagingedges in order to permit them to extend into the angle between the weltand upper, hereinafter referred to as the welt crease. The wiper plates94 are pivotally connected by a halved joint 118 (Fig. 5) at a pointsubstantially in alinement with the longitudinal center line of the heelseat. The wiper plates are supported upon a table 120 fixedly secured tothe machine frame and having a lengthwise groove 122 (Fig. 4) formednear its Such sidewise movement of i rthe wiper plates imparts a likemovement to a lpair of tackers 224 arranged to drive Y tacks -throughthe welt, upper and insole atv opposite forward end for the reception ofthe downwardly extending head of the rivet 124 upon which the wiperplates are pivoted. The wiper plates are thus maintained in position toembrace the heel end of a last and upper as the last and upper arebrought into position to be operated upon, while being permitted to movelengthwise kof the last within the limits afforded by the groove 122.The wiper plates 94 are urged toward each other by compression springs126 and 128 (Fig. 3) through connections hereinafter described. Theclosing movement of thefwiper plates by said springs is limited byabutment screws 130 and 132 threaded into ears 134 and 136 respectivelydepending Afrom the outer. edges of the wiper plates near their forwardextremities.

The welt presser 116 is pivoted at its rearward end to a pair of links138 (Figs. 4 and 6) positioned at opposite sides `of the rear end of thewelt presser. At their lower ends the links 138 are pivoted atl oppositesides of the table 120. A limited longitudinal movement is thus affordedthe welt presser 116 in order to permit an adjustment thereof relativelyto the last and upper to be operated upon. The welt presser is urgedforwardly and upwardly, by a spring 140 (Fig. 4) Aattached to theweltpresser and extending therefrom forwardly and upwardly and attachedat its upper end to the machine frame. The forward movement of the weltpresser 116 under the tension of the spring 140 is limited by a stop 142in the form of a boss formed at the forward end of a slide 144 andarranged to extend downwardly through an opening 145 (Fig. 5) in thetable 120. The slide 144 is arranged for longitudinal movement in agroove formed in the under surface of `the welt presser. The stop 142 isclamped in adjusted position by a clamping screw 146 (Fig. 4) .extendingdown'- wardly through a slot 148 formed in the welt presser and havingthreaded engagement within a tapped hole formed in the slide 144. Thestop 142 abuts the rearward edges of the wiper platesl 94 at a pointdirectly back of the halved joint 118 and has its forward movementarrested by the engagement of thel depending head of the rivet 124 withthe forward extremity of the groove 122formed in the table 120. Thespring y140 thus operates through the stop 142 to hold the wiper plates94 `yieldingly at the forward limit of their movement and it alsooperates to urge the wipers forwardly into the welt crease when a lastandupper are in operative position as best shown in Fig. '4. The weltpresser 116 is actuated by a cam 149 (Fig. 2) secured to the main shaft100 through a bell crank lever 150 pivoted to a bracket'152 by a crc-ssshaft 154.

rThebracket 152 is secured at its upper end to the machine frame bylscrews 156 extending through ears 158 (Fig. 3) projecting outwardlyfrom the bracket. At its lower end the bracket is secured to the table120 by screws 160 extending upwardly through the table. The bracket 152thus operates to support the forward end of the table 120 and to resistdepression of the table by the welt presser 116. The bracket 152 (Fig.3) has the vgeneral shape of y an inverted U having the endsof itsvertical members secured to the table 120 and having the cross shaft 154mounted in its vertical members about midway of their height. The bellcrank lever 150 is held against transverse movement relatively to thebracket 152 by the vertical members of the bracket and is yieldinglyheld in Contact with the cam 149 bya spring 162 attached tothe bell 2)extending forwardly from; the bracketf1f52`..` The camf 149 acts on aroll 166 (Fig 4)` pivoted "to the endlof one arm of the-bellicrankleverand.

upper, a l1ook.170f(Fig. 1') isautomatically actu#` ated by acompression spring. 180 to pullA the spindle 26 rearwardly of themachine, thereby' forcingr the wiper. plates94 fartherfintothe weltcrease and pressing the heel and ofi the upper against a back seam wiper1*'12. The hook 1'70 is pivoted at- 1.74 toithemachinercolumn 20 vandhas. `its. active surf'ace- 176. formed Iasv a cam `face .a and arrangedto engage a roll 1:'8`c`arried by tiie pin 29 on the'spindle carrier'24'. `The meansfor actuating the hook 170 may be substantially` thesame as the mechanism for actuatingv a similar hook, disclosedY inPatent` No. 1,602,618; hereinbefore referred to. Briey described,r` saidactuating means comprises a link 182 pivoted at its lower end to arearward extension of the hook and pivoted at its upper end to a bellcrank lever 18,4, which in turn is pivoted at 186 to the machine frame@r`The vertical arm of the bell crank lever 184 carries a cam roll 188whichy engages a cam 190, (Fig. 2) Sai-d cam operating to time theactuation ot the hook 170 by the compression spring 180.

The movement of thehook `1'70 is utilized. to .reset the clutch-andlimit the rotationl of `the main shaftlDO to a singlerevolution. Theconnections from the hook, 1'10`for resettingk the clutch aresubstantiallynthe same-as in'Patent No. 1,602,618 abovereferred to andcomprise a lever 192 '(Fig. 1) arranged'to. be` actuated by the hook 170toimpart aforward? movement to the clutchV rod 102 in order toireleasethe plate 114 from the.V latch member` 112 andpermit the clutch, rodtobe lifted by the springy 194.

Asl the back seam Wiper; comes to the mechanism, which may lbe'substantially the same asfthat disclosed in Patent No, 1,356,510, abovereferred to, is; actuated-tof drive` av tack through the.` back of` theupper'andrinto the last at one l side-i of the back seam; The tack isdriven .throughsa 'square` cut notchoprovidedy in. the..upper edge, oithevback, seam wiper and` .provided in the slide 196 to provide thenecessary" j Ylimit vof .itsxdownward stroke a tack `'driving l extendeddownwardly tothe elevationoi the` of the welt presser 116 andthereturnoii they shoe'y tog the-position illustrated` in` Fig. 2.

After thehorizontal tack has been driven the k weltf and upper aretacked at thecenter of they rearl end of the, heel seat by a .tackdriver 98 of `usual: construction, and at oppositesides. of the heel:seau. byapairl of tack drivers 224 also,` of

Iusual' construction.. vz'llhegtack driver98 and the tack drivers, 224areactuated in unison .by an actuatorarrn 226.v An' adjustable 'abutmentyin ther-form of asplit clamp 228 is mounted at the upper'end of theguide 230 within which the tack.` driver "98s isarranged to slide. Theabutment. 228' determines thelirnit ofthe strokes of the tack. drivers98iand 224 and thus determines lthe extent to which the tacks projectabove the i surface of the welt- Preferably the split lclamp 228- vis so.adjusted thaty the `tacks are driven. through the welt, yupper andinsole and into the last bottom'.` Accordingly, it is desirable that theusual heeli plate be omitted from thelast. 1f it is desirable, as an`-aid4 to subsequentv operations uponthe shoe, `that the last beprovided with a heel plate, the split clamp 228 `is preferably 'seadjusted that the. tacks will be driven through the welt `and upper andinto the insole and will come to rest without having struck the heelplate. The tack drivers 224 have each a ball and socket connection withthe actuatorarm 226,`

said connection comprising a ball 236 formed `at the upper end of eachof the tack drivers, and screws 232 mounted in the forward ends of theactuator arm' (Fig. 8) and arranged to be secured; inL adjustedvposition by` split` clamps formed in the arm. The screws 232 areslightly concaved at their lower ends to provide a bear- .ing for theballs 236, said balls being held in Contact with the screws 232 byinverted caps 234 internally threaded for engagement with the screws232, each of the caps 234 being provided rat its lower end with arounded ange which forms a seat for the ball 236. The cap 234 may besecured in adjusted position upon the screw 232 by a Cotter pin 238extending through open end slots provided at opposite sides of the cap234 and through a hole provided in the screw 232. By releasing theclamping screwsv 239 which secure the screws 232 to the actuator arm 226each of the screws 232 may be adjusted in order to impart to each of thetack drivers 224 an independent adjustment in the direction of itsstroke.

In order that the tackers may automatically arrange themselves inpredetermined positions whereby the tacks may be driven into the welt atpoints substantially adjacent to the seam connecting the welt to theupper without danger of driving them through the seam itself,connections are provided between the wiper plates 94 and the tackerswhereby the tackers partake of the movement of the wiper plates as alast` may be adjusted lengthwise of the last and the Y central heel seattacker will partake of that adjustment.

In the illustrated machine the arrangement of the side tackersrelatively to the seam uniting the welt and upper is effected byconnections from the wiper plates 94 whereby the spreading of the wiperplates as the heel end of a shoe is brought into engagement therewithcauses the tackers to move away from each other andv arrange themselvesin predetermined relation to the welt regardless of the width of theheel to be operated upon. The connections between the tackers and thewiper plates comprise a pair of L-shaped members 242 (Fig. 3) pivoted totack driver guides 244 near their lower extremities and having theirhorizontal arms extending outwardly and drilled longitudinally for thereception of a cross rod 246. A pair of slides 248 have tongue andgroove connections with downwardly extendingears formed in the L-shapedmembers 242 (Fig. 2) and are adjustably secured to said ears by clampingscrews 250 extending through slots provided in the slides. The slides248 are yieldingly held against the outer edges of the wiper plates bythe compression springs 126 and 128 mounted on the cross rod 246 andheld between nuts 254 and the outer edges of the L-shaped members 242.

In order that the tackers may be moved downwardly in order to bring theminto operative relation to the work prior to the driving of the tacksand in order that the tackers may be retracted after the tackingoperation to permit the removal of the work without interferencetherefrom connections are provided between the tackers and the free endof the welt presser-116 whereby the tackers partake of the verticalvmovement of the welt presser.

The connections between the central heel seat tacker 98 and the weltpresser consist of the lugs 240 extending upwardly from the welt presserand the rearward extension of the sleeve 230 pivoted to said lugs, ashereinbefore described. The nozzle of the central heel seat tacker ispositioned within a bell-mouthed opening 256 (Fig. 4) extending The sidedownwardly through the welt presser.
